"BUFFALO, N.Y. — Preparing the F-35, the U.S. Navy’s most advanced fighter, for missions in today’s complex electromagnetic spectrum environment requires an equally advanced test environment. Northrop Grumman’s multispectral testing solution recreates the most accurate mission-like conditions in the laboratory and on the range. Recently, Naval Air Warfare Center Weapons Division Point Mugu, California, took delivery of the most sophisticated test environment the company has ever created, the company reported in a May 7 release.

The environment consists of Northrop Grumman’s Combat Electromagnetic Environment Simulator (CEESIM), Signal Measurement System (SMS) and other stimulators, all under control of the Synchronizer Controller System (SCS).

“Keeping the F-35’s systems ready requires a fully integrated test environment like we have developed with CEESIM, SMS and SCS,” said Joe Downie, director, land and avionics C4ISR division, Northrop Grumman Mission Systems. “These systems work together to provide the environment complexity and density, measurement and analysis capability, and test control capability necessary to evaluate the F-35 in a realistic mission scenario.”

At the center of the environment is the CEESIM, which simulates multiple, simultaneous RF emitters as well as static and dynamic platform attributes to faithfully model true-to-war conditions. CEESIM’s Advanced Pulse Generation high speed direct digital synthesizer technology is used to generate realistic electronic warfare mission scenarios.

The SMS provides wide bandwidth signal measurement, recording and analysis capability which is used to validate the test environment and evaluate the system under test performance.

The SCS provides the tools to program an integrated multispectral test scenario, including threat radars, communications signals, radar and electro-optical/infrared signatures. The SCS also manages the execution of the scenario by all of the stimulators to ensure a coherent multispectral test environment."

"...Lockheed Martin has also created a specialized facility to help test and ready Surface Electronic Warfare Improvement Program deliveries for the Navy.

The first facility was built in 2012 and was used as part of the low-rate production units with 38 systems going through the chamber, Joseph Ottaviano, director of electronic warfare systems at Lockheed Martin, told C4ISRNET during an April 9 interview at the Navy League’s Sea-Air-Space conference.

The chamber can replicate threats and test sensitivity levels that were previously impossible. Moreover, the facility is adjacent to the manufacturing plant, making it easier and faster to test after production."
